FIELD OF INVENTION

The present invention is generally related to a towing apparatus and,more particularly, to an underbed hitch mounting system. Moreparticularly, this disclosure is directed to an improved structuralframe system and trim rings for an underbed hitch mounting system

BACKGROUND

Many vehicles are designed to transport freight, goods, merchandise,personal property, and other such cargo. Often, a hitch assembly isutilized to connect a towed vehicle or trailer to a towing vehicle, suchas a truck for example, to increase the capacity to transport goods.Many types of coupling devices have been developed for providing thisconnection between a towing vehicle and a towed vehicle.

It is well known to utilize a trailer hitch to connect a trailer to atowing vehicle. There are many different types of trailer hitches thatmay be attached to the towing vehicle in a variety of ways, depending onthe type of hitch to be used. Some of the most common types of hitchesinclude gooseneck, fifth wheel, front mount, and the like. Often, thetype of hitch used to connect a trailer and a vehicle is determined bythe size, shape and other features of the trailer. For example, largetrailers such as semi trailers and campers often require a fifth wheelhitch, whereas, small and midsized trailers, such as boat trailers, arebetter suited for gooseneck trailer hitches. Typically, trailers areconnected to a towing vehicle by way of a ball hitch secured to thevehicle and a ball socket coupling mechanism on the trailer that mountsover the ball and thereby allows for the trailer to pivot behind thetowing vehicle.

Due to the size and weight of many trailers, towing a trailer may causeunsafe conditions for the towing vehicle, such as fishtailing or otherunsafe effects. To avoid these unwanted effects, it is preferable toevenly balance and distribute the weight of the trailer over the wheelsof the towing vehicle. This is best accomplished by connecting the hitchto the frame or base of the towing vehicle, near the vehicle's center ofgravity. Accordingly, fifth wheel and gooseneck hitches mounted topickup trucks are often connected to the truck frame underneath the bedof the truck.

Traditional fifth wheel hitches include a head assembly for receiving aking pin on a trailer, a base having a plurality of legs, and one ormore mounting rails. The mounting rails may be permanently fixed to theframe of a vehicle, such as a pickup truck. For example, the mountingrails may be connected between two portions of a pickup truck frameunderneath the truck bed. The mounting rails may include a plurality ofholes for receiving the legs of the fifth wheel hitch.

Corresponding openings may be cut in the truck bed and aligned with theholes in the mounting rails. The legs of the fifth wheel hitch may beconnected to holes in the mounting rails through the openings in thetruck bed, thereby securing the fifth wheel hitch to the frame of thetruck. When the fifth wheel hitch is not in use, the legs may bedisconnected from the holes in the rails and the hitch may be removedfrom the bed of the truck. Caps may be placed over the holes to allowthe truck bed to be used for other purposes.

Traditional gooseneck hitches also mount to a pickup truck frame,beneath the bed of a truck. A gooseneck hitch is designed for use in apickup truck similar to a fifth wheel. The difference is that thegooseneck uses a ball and coupler verses a kingpin and pin receiver.Gooseneck hitches include a mounting plate configured to connect to theframe of a truck, a receptacle in the mounting plate configured toreceive a ball hitch, and a hitch ball removably connected to thereceptacle and configured to engage a coupling member of the trailer. Anopening in the bed of the truck is aligned with the receptacle in themounting plate, allowing the hitch ball to connect to the receptaclethrough the opening in the truck bed. The hitch balls themselves aretypically removable or retractable so that when the hitch is not in use,the hitch ball may be removed or retracted when not in use, so as not toobstruct the bed of the pick-up truck in any significant manner.

Towing vehicles are generally arranged to accommodate either a fifthwheel hitch or a gooseneck hitch, but not both. To convert a towingvehicle from accommodating a fifth wheel hitch to a gooseneck hitch orvice versa is time and labor intensive and inefficient. Furthermore,both fifth wheel hitches and gooseneck hitches are preferably mounted tothe vehicle frame near the vehicle's center of gravity. However, sincefifth wheel hitches and gooseneck hitches use different mountingconfigurations, traditionally only one hitch can occupy this location.

Some underbed structural bodies are made by components that increasetime to market and have higher tooling costs. Additionally, somevehicles, such as light duty trucks that may not be equipped with aframe configured for a 5^(th) wheel hitch or gooseneck attachment maynot be easily configured to receive support frame components as thelayout of the available vehicle structure may not allow for particularstrength of configured components. Known designs are described by U.S.Pat. Nos. 7,793,968 and 7,828,317. Further, examples of these designsmay be found in commonly owned patents including U.S. patent applicationSer. No. 14/739,076, entitled, “UNDERBED HITCH MOUNTING SYSTEM,” filedJun. 15, 2015 which is a continuation of U.S. patent application Ser.No. 13/790,134, entitled “UNDERBED HITCH MOUNTING SYSTEM,” filed Mar. 8,2013, now U.S. Pat. No. 9,067,468 which is a continuation of U.S. patentapplication Ser. No. 12/609,062, entitled “UNDERBED HITCH MOUNTINGSYSTEM,” filed Oct. 30, 2009, now U.S. Pat. No. 8,414,009 which claimsbenefit from U.S. Provisional Patent Application No. 61/197,732,entitled “UNDERBED HITCH MOUNTING SYSTEM,” filed on Oct. 30, 2008, whichare all hereby incorporated in their entirety by reference.

These patents describe “H” frame structures with integrated castings andsafety chain/5^(th) wheel pucks. The casting designs are either with anintegrated safety chain/5^(th) wheel mounting system or are separatefrom the castings along with the use of square or rectangular shapedtube mill standard tubing to connect the center gooseneck with the foursafety chain mounts. These castings are usually expensive and have along lead time for tooling.

Therefore, there is a need in the art for an improved apparatus fortowing vehicles that allow for selectively accommodating either a fifthwheel hitch or a gooseneck hitch that reduces cost and time formanufacturing.

Further, underbed structural frames may be exposed to the bed portion ofa vehicle. The configuration of the bed liner or contours of the vehiclebed may hamper bed usage by damaging cargo.

Therefore, the disclosed embodiments may solve the problems of the priorart and includes an assembly that may selectively cover exposed portionsof the underbed structural frames.

The mounting apertures 36 may be of any appropriate shape or size,such as a generally circular, ovular or rectangular shape. There may beany number of appropriate mounting apertures 36 and should not belimited to that shown and described herein.

The mounting apertures 36 may be utilized for connecting another memberto the rails 32, such as the frame mount brackets 50 (see FIGS. 7, 8Aand 8B). The mounting apertures 36 may also be used to connect the rails32 of the hitch mounting system 10 to the underbed of the towing vehicleframe. For example, the rails 32 may be connected to the towing vehicleframe, such as underneath the truck bed (FIG. 7).

The rails 32 may include one or more frame mount brackets 50 (FIGS. 4,5, 6, and 7). The frame mount brackets 50 may be utilized for connectingthe rails 32 to the frame 52. The rails 32 may be connected to the framemount brackets 50 by any appropriate means, such as with fasteners,welding or the like. The frame mount brackets 50 may be of anyappropriate shape or size, such as a general L-shape, rectangular plateor the like. The frame mount brackets 50 may be sized and shaped toengage a vehicle frame.

Typical vehicle frames 52 may include two parallel steel members (FIG.6). An end of the structural frame member 20 may connect to a firstmember of the frame 52 and an opposite end of the structural framemember 20 may connect to a second member of the vehicle frame 52. Therail mounts 30 and rails 32 may extend between the frame mount brackets50. The rail mounts 30 and rails 32 may be of a length sufficient tospan the distance between the frame mount brackets 50 when thosebrackets engage the vehicle framework 52. The frame mount brackets 50may form a generally L-shaped bracket to engage the frame 52. The framemount brackets 50 may be attached to the frame 52 by any approaprtiemeans, such as with fasteners, welding or the like.

The mid rail or adapter plate 40 may be of any appropriate shape orsize, such as a generally rectangular or tubular shape that may span thelength between the rail mounts 30 (FIGS. 1A-C4). The mid rail or adapterplate 40 may be configured to connect to the rail mounts 30. The midrail or adapter plate 40 may be attached to the rails by any appropriatemeans, such as with fasteners, welding or the like. Additionally, theadapter plate 40 may be a generally continuous and uniform monolithicconstruction with the rail mounts 30.

The adapter plate 40 may be of a one piece construction or may includeseveral sections that may be secured together by welding, fasteners orthe like. When the mid rail 40 is connected to the rail mounts 30, therail mounts 30 may be approximately flush with and parallel to oneanother.

The mid rail 40 may also include a base member 46. The base member 46may be of any appropriate shape or size, such as a generally square,rectangular or tubular shape. The base member 46 may be a plate and maybe attached to the bottom of the mid rail 40. The base member 46 may beattached to the mid rail 40 by any appropriate means, such as bywelding, fasteners or the like. The base member 46 may also be securedto the rail mounts 30, such as on the underside of the rail mounts 30(FIG. 1B). In one embodiment, the base member 46 may have a continuous Htype shape having portions that extend along the bottom of the railmounts 30 and a portion that extends along the bottom of the mid rail40. The base member 46 may have a shape that extends passed the edges ofthe bottom of the mid rail 40 as illustrated by FIG. 1B.

The mid rail 40 may include a receiver 42 that may be configured toreceive a hitch ball. For example, the receiver may be a hitch ballsocket that may be configured to receive the hitch ball. The hitch ballsocket 42 may be of any appropriate shape or size, such as a generallycylindrical shape. The hitch ball socket 42 may be located at anyappropatie position on the adapter plate 40, such as the approximatecenter of the adapter plate 40. For example, the hitch ball socket 42may be configured to receive a removable hitch ball with spring-loadedball bearings. It should be appreciated, however, that the receptaclemay be configured to receive any appropriate type of hitch ball andshould not be limited to that described herein.

The hitch ball socket 42 may include a raised collar 48. The raisedcollar 48 may be of any appropatie shape or size, such as one that mayextend above and approximately perpendicularly to the surface of theadapter plate 40. The raised collar 48 may protrude through or beaccessible through an aperture in the bed of a vehicle.

The underbed hitch mounting system 10 may utilize a puck mounting systemwhereby the trailer hitch may be installed in the pickup truck bed withonly four small holes (not shown). Utilizing a puck mounting system mayprovide uninhibited use of the truck bed when the hitch is dismounted.The puck mounting system may also provide for a wider platform andmounting surface, which increases the stability. The puck mountingsystem may be used with any appropriate trailer hitch mounting kit, suchas those that utilize rail mounts 30 or cross members for example, suchas with the “Signature Series” produced and sold by Cequent.

The underbed hitch mounting system 10 may include at least two railmounts or cross members 30. The cross members 30 may include rails 32and sockets 34 for attachment with a puck or receiving member. The crossmembers 30 may be attached to the vehicle framework 52 by anyappropriate means, such as with fasteners, by welding or the like.

Holes may be drilled in the truck bed corresponding to the locations ofthe sockets 34 in the rails 32 and the hitch ball socket 42. A fifthwheel hitch may be removably connected to the sockets 34 in the rails 32through the holes located in the truck bed. A hitch ball may beremovably connected to the hitch ball socket 42 through the hole in thetruck bed, whereby a gooseneck hitch may be utilized.

FIGS. 1A, 1B, and 1C illustrate an embodiment of the underbed hitchmounting system 10. The rail mounts 30 are made from bar stock weldedtubing or sheet metal parts. The bar stock may be machined or heattreated. The bar stock material may be used at frame mounting points andfifth wheel attachment areas with welded tubing or sheet metal parts.This may allow the system to meat normal layout constraints of existingvehicle frame configurations but also meat strength requirements forconnection to the frame and support for the appropriate fifth wheelhitch or gooseneck assembly. Further, the use of bar stock and pressbroken sheet metal allows for a quick production lead time and lowertooling costs. In one embodiment, the rail mounts 30 and mid rail 40 aremade of sheet metal material and the rail members 32 are made of a solidbar stock material that has been heat treated and machined.
